Abstract

Numerical calculations of the innovative flue gas recirculation (FGR) system through an inactive coal pulverizer for a 40% load of the OP 650 boiler at the Jaworzno III Power Plant were carried out. The research was conducted to determine the effect of FGR on the formation of NO x , CO emissions, and low-NO x waterwall corrosion. Using numerical modelling, the influence of the place of injection of recirculated flue gas on the formation of NO x was also investigated. The tests were carried out based on data from the boiler monitoring system and calculation results using a 0-dimensional model. Modelling of the FGR was performed for five variants. FGR equalized the temperature in the furnace, eliminating temperature peaks in the burner belt. Moreover, FGR did not increase the CO content in the flue gas and reduced the O 2 concentration in the area zone of pulverized coal combustion. For FGR systems, the emission of NO x below 200 mg/m 3 n for 6% O 2 in dry flue gas was kept. This proves that the recirculation helps to meet the BAT (best available techniques) requirements for NO x emissions. It has also been shown that FGR does not pose a risk of low-NO x corrosion in the next 20 years.
